What is URL Encoding?
URL encoding (also known as Percent-encoding) is a mechanism for encoding information in a Uniform Resource Identifier (URI). Since URLs cannot contain spaces or certain special characters (like ?, =, &), they must be converted into a valid format, substituting the unsafe characters for a % followed by their hex equivalent (e.g., a space becomes %20).

This tool uses encodeURIComponent, which is generally safer for encoding query string parameters as it encodes characters like ?, &, =, and +.
